Read Exodus 34:29-35
29 When Moses went down from Mount Sinai carrying the Ten Commandments, his face was shining because he had been speaking with the Lord; but he did not know it. 30Aaron and all the people looked at Moses and saw that his face was shining, and they were afraid to go near him. 31But Moses called them, and Aaron and all the leaders of the community went to him, and Moses spoke to them. 32After that, all the people of Israel gathered round him, and Moses gave them all the laws that the Lord had given him on Mount Sinai. 33When Moses had finished speaking to them, he covered his face with a veil. 34Whenever Moses went into the Tent of the Lord’s presence to speak to the Lord, he took the veil off. When he came out, he would tell the people of Israel everything that he had been commanded to say, 35and they would see that his face was shining. Then he would put the veil back on until the next time he went to speak to the Lord.
Moses' face was shining after he spent time with the Lord. As Christians we are invited into God's presence through Christ; we are empowered by the Holy Spirit to reflect God's glory from day to day.
We do this not in our own power; but as a result of opening ourselves to God in prayer.
Lord let your light shine through me despite my failures and faults.
